IC Card Polyphase Prepaid Electricity Meters With Iec Standard Load Profile Modular
The CA368-C is a new generation of prepaid electricity meter that integrates high precision metrology features with 3DES security encryption. The meter has option for high profile configurations of load profile and plug & play communication modules.It has both direct connection and CT connection type for a broad range of voltage and current consumers.
The meter is available with a plug-in module for data collection and network communications . This modular-design offers utility a wide range of communications such as PLC/RF/GPRS/3G and 4G LTE cellular data networks dependant of local infrastructures. Upgrade and maintenance will also be cost-effective by repairing or replacing the modules only instead of the entire meter.
Main Features
a) Maximum demand measurement
b) Tamper prevention: magnetic proof, cover open detection
c) Load profile record at adjustable intervals
d) Data retention in outage and absence of power
e) TOU with multi-rate and multi billing cycles
f) Plug & play communication modules
g) IEC 62056-21 and DLMS/COSEM compliant
Utility Benefits
1) On demand and remote load controll
2) Low operational and maintenance costs
3) Flexible communication selection according to local conditions
4) Revenue protection by flexible consumer contract control
5) Prepared for AMR/AMI functionality
6) 15 years designed life
